David Button was frustrated with how the result slipped away from Fulham on Saturday afternoon.
Neeskens Kebano’s effort had put the impressive Whites in front on 25 minutes, but a deflected Sergi Canos strike meant Brentford went into the break level.
And the hosts took control early on after the restart, with Romaine Sawyers’ goal and Denis Odoi’s red card setting them up for a 3-1 derby win.
“After going 1-0 up we obviously need to defend our lead better,” Button stated. “We need to be a bit cleverer with how we defend. In the second half we concede following a set-piece and then get the red card, which made it a difficult day for us.
“We played well in the first half but didn’t manage to see it through to half-time, which would’ve given us a good platform to build on.
“Playing away from home with 10 men is always going to be hard, so that was perhaps the turning point because I thought up until then we were well in the game, and that made it really difficult for us.”
The defeat was a hard one to take at the home of our rivals, and Button is desperate for an immediate response when Birmingham City come to Craven Cottage at the weekend.
“It’s a league where the games come thick and fast,” he said. “We’ll have to pick our heads up and try and get back to winning ways against Birmingham.
“Every match in this division is difficult, and Saturday will be no different. I’m sure they’ll come and work hard and make it tricky for us, but it’s one that we’re also confident of winning.”
